I keep getting an error message saying, "Could not read from resource."

It mean that it can not load the

It means that it can not load the DVD for some reason. Can you give us the output of the following command in Terminal?:

  sudo mount /dev/cdrom /mnt

I've been trying to solve the same problem. Here's what I get in the terminal:

mount: block device /dev/sr0 is write-protected, mounting read-only

it said command not found.

@Anne: Navigate to the /mnt directory with nautilus and see if you can see the content. Then try install ubuntu-resticted-extras and try again. In terminal try this:

  sudo apt-get install ubuntu-restricted-*

@Josh: You probably mistyped something. Try copy-paste the above command in Terminal. You will be prompted fro your password afterwards.

@Theodotos I did not mistype anything. I typed it straight from this site and still keep getting that response. I am not being prompted for my password.

The correct command is "sudo<Space>mount<space>/dev/cdrom/<space>/mnt

The sudo and mount commands are essential commands on your system and there is no way you can get a "Command not found" response unless you mistype something. Can you please try again?

the response was mount: unknown device.

It seems that your cdrom is not detected! Can you try this command and give us the output:

  sudo lshw -c disk

I was thinking that maybe your CD-Rom is not detected but it is there. Does it work any other CD's. Can you try putting a data Cd for example and see if it's working? I reckon you have a hardware problem with your CD-ROM

yeah it is a hardware problem most likely. it reads a data cd just fine.
